Overview

What is Light Server?

Light Server, a new-gen cloud server service for small- and medium-sized enterprises (SMEs) and developers. It features out-of-the-box service for cloud-based lightweight business scenarios, such as websites, Mini program/mini games, ecommerce, cloud storage, image hosting, and various development, testing as well as learning environments. It is easier to use than traditional cloud server services and integrates common basic cloud services into bundles with different data transfer quota. Such bundles contain popular open-source software programs, enabling you to build applications swiftly and enjoy the best way to get started with Yisu Cloud.

Why Light Server?

Light Server features the following advantages:

1. One-Click App Deployment: A rich set of out-of-the-box app images and preconfigured software stacks for websites, blogs, and other application systems allow you to deploy apps in seconds.
2. Easy to Use: One-stop integration of basic cloud services, including computing, storage, and network, makes creating and managing cloud servers and applications simple and intuitive.
3. Cost Effective Bundles: Bundles for computing, storage, and network resources make your deployments highly cost-effective.
4. Stable, reliable, and secure.

Differences from ECC

For more information on the differences between Light Server and ECC, see Comparison with ECC.

Instance

A Light Server instance is a virtual computing resource in the cloud, containing the most basic components such as CPU, OS, network, and disk. Lighthouse instances are generally suitable for lightweight application scenarios with a moderate number of access requests, including small websites, web applications, blogs, forums, and cloud-based development, testing, and learning environments. For more information on how to select an instance specification, see Lighthouse Bundles.

For scenarios like high-concurrency websites, video encoding/decoding, large-scale games, and complex distributed cluster applications, it’s recommended to use ECC. ECC provides rich instance models, such as Memory Optimized, High I/O, Big Data, Bare Metal, and GPU/FPGA Heterogeneous Computing. For more information, see Cloud server selection suggestions.

Image

An image is a preconfigured template used for the launch and running of Light Server instances. It contains the preinstalled operating system and software applications. Simply put, you can consider an image as an “installation disk” for Light Server instance. You can use an image to create one or multiple instances.

Application image

• Description
  An application image provides everything you need to launch a Light Server instance, including the OS (CentOS and Windows Server), applications (such as LAMP, LEMP, WordPress, Tomcat, ASP.NET, and Node.js), their runtime environments, and relevant initialization configuration files.
• Use cases
  It is suitable for quick out-of-the-box application deployment. After a Light Server instance is created from an application image, the application system can be initialized automatically, and you can build the application in just a few steps of simple configuration, with no need to perform operations such as manually installing applications and uploading software packages.
• Available images
  • LAMP
  • LEMP
  • Node.js
  • Tomcat
  • Django
  • Docker
  • WordPress
  • Drupal
  • ASP.NET
  • Typecho
  • Swoole
  • Workman
  • ThinkPHP
  • Plesk
  • K3s

System image

• Description
  A system image contains only the initial operating system (CentOS, Ubuntu, and Windows Server). It does not have preinstalled applications, their runtime environments, and relevant initialization configuration files.
• Use cases
  It is suitable for users familiar with the installation and environment configuration of server operating systems and software programs. Light Server instances created from a system image have only the initial operating system environment installed, where you can install software programs or application systems as needed.
• Available images
  • CentOS 8.2 (x64)
  • CentOS 7.5 (x64)
  • CentOS 7.2 (x64)
  • CentOS 7.0 (x64)
  • CentOS 6.8 (x64)/(x86)
  • CentOS 6.5 (x64)/(x86)
  • Debian 10.2 (x64)
  • Debian 9.0 (x64)
  • Debian 8.6 (x64)/(x86)
  • Debian 8.2 (x64)/(x86)
  • Ubuntu Server 20.04 LTS (x64)
  • Ubuntu Server 18.04.1 LTS (x64)
  • Ubuntu Server 16.04 LTS (x64)/(x86)
  • Ubuntu Server 14.04 LTS (x64)/(x86)
  • Windows Server 2016 Datacenter
  • Windows Server 2012 R2 Standard/Datacenter (x64)
  • Windows Server 2008 R2 Enterprise/Datacenter with Service Pack 1(x64)

Network

The network of Light Server is based on Yisu Cloud VPC, which is stable and secure.

Public IP

An independent public IP is assigned to each created Light Server instance, and a dedicated public network bandwidth value is configured by default for access over the internet. You cannot add more public IPs or change the public IP.

Private IP

• Each Light Server instance is assigned with one private IP for communication with other Light Server instances.
• Under the same account, Light Server instances are grouped by the region and deployed on different VPCs.
• Private network bandwidth is the bandwidth of a shared network, and there is no guarantee for its continuous stability.
• Network isolation between Light Server instances can be implemented by a firewall.

Data transfer

Data transfer of a Light Server instance is included in the bundle. The quota of data transfer refers to the monthly upper limit on the public network outbound traffic. When the quota is used up, the excessive part is billed on the pay-as-you-go basis. For more information, see Billing Overview.

Storage

Cloud Block Storage (CBS) is a cost-effective and customizable block storage device service, featuring high availability and reliability. It provides efficient and reliable storage device for Light Server instances. CBS provides long-term storage at the data block level. It is typically used as the primary storage device for data that requires frequent and fine-grained updates (such as file system and database). CBS uses a three-copy distributed mechanism to back up your data on different physical machines to avoid data loss caused by a single point of failure.

System disk

• The lifecycle of a system disk is follows the lifecycle of the bound Light Server instance. It is purchased with the Light Server, and cannot be attached or detached.
• All system disks included in Light Server bundles are SSDs, which are based on full NVMe SSD storage media and use a three-copy distributed storage mechanism. It features low-latency and high-throughput I/O capabilities with a high random IOPS and 99.9999999% data security.
